CONVEYER.

SPECIFICATION forming part of Letters Patent No. 535,320, dated March 5,1895.

Application filed September 12,1893. Serial No. 485,357. (No model.)

.To all whom, it 11i/wy concern.-

Be it known that I, WILLIAM B. CoMsrocK, a citizen of the United States,and a resident of Oak Bar, in the county of Siskiyou and State ofCalifornia, have invented certain new and useful Improvements inConveyers; and I do hereby declare the following to be a full, clear,

.and exact description of the invention, such fas will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to elevators adapted for raising water, gravel orother material, and for employment in connection with suitable motivepower, such as steam engine,water wheel or wind wheel, or be used byhand power with small wheels.

The object of the invention is to provide efficient means for elevatingwater or other materials and depositing the same at an elevation in asuitable receptacle.

With this and other objects in view the invention consists of theconstruction and arrangement of the several parts, which will be morefully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a conveyer embodyingthe invention. Fig. 2 is a sectional elevation of the upper and lowerpulleys and the chains and buckets in position. Fig. Sis a detailperspective View of the upper pulley with one rim thereof removed. Fig.4 is a detail perspective view of one of the buckets and a portion ofthe chain links.

Similar numerals of reference are employed to indicate correspondingparts in the several figures of the drawings.

Referring to the drawings, the numerals l and 2 designate the upper andlower pulleys which have beariugin a suitable framework of anydimension, and said pulleys may be situated at such distances apart asto accommodate the work to b e performed and the d epth of the well orshaft with which they are used. Each of the pulleysl and 2 is suppliedwith rims 3 which stand beyond the peripheries of the main bodies of thepulleys and the upper pulley has mounted therein a series ofdump-troughs 4 which incline toward one side and extend through one ofthe rims or heads. One side of each dump-trough is supplied with aguard-strip 5 at the top edge thereof, and adjacent to the saiddump-trough is a chute board 6 over which the projecting ends of thesaid dump-trough extend, the said chute-board being inclined outwardlyfrom the upper pulley and situated over a receiving trough 7 which maybe of suitable dimension and may extend away from the said upper pulleyany suitable distance. The chuteboard 6 is of a considerable length inorder to catch all of the water or other material which is deliveredfrom the dump-troughs 4 even after the latter have passed the center ofposition above the axis of the pulley and thereby permit the saiddump-troughs to become thoroughly emptied and to deliver their contentsto the said chute-board. The adjacent sides of the dump-troughs aremounted against arms 8 which support the rims 3, and said arms extendfrom central heads 9 which are fixed to the axis 10, such being theconstruction of the upper pulley, While the lower pulley is similarlysupplied with the rims 3 as stated and the heads and axes.

Chain buckets 1l operate in conjunction with the pulleys l and 2 and areformed of upper and lower inwardly sloping ends l2, the bottom endsbeing closed and the upper ends open. The opposite sides of the upperportions of each of the buckets are supplied with eyes or loops 13'through which are passed link-rods 14, connected at the bottom to across-strip 15, and at the top to a similar strip 16, said strips 15 and16 forming means for limiting the movement of the buckets on the linkedrods 14 in the rising and falling movement of said buckets. The ends ofthe linkrods are connected to similar link rods in succession by loops17, which permit of a flexible or hinged action of the buckets intraveling over the pulleys land 2. The inner short sides of each of thebuckets are of such dimension as to extend some distance downwardly intothe dump-troughs when they pass over the pulley 2 and below theguard-strips 5 of the said dump troughs. This operation causes the fullcontents of the buckets tobe delivered into the dump-troughs and at thesame time sufficient purchase is obtained on the buckets to continuouslyrotate the series of buckets, which form a belt against the resistanceoffered by the weight of the contents thereof and thereby preventbackward slip ping. As the contents of the buckets are delivered intothe several dump-troughs, dash ing or spilling over from the said dumptroughs is prevented by the guard strips 5.

The entire construction and arrangement of parts as herein shown anddescribed can be arranged in any suitable manner, either at an inclineor vertically, and large orsmall to suit di'erent purposes and differentcharacters of work. The several parts may be constructed of either woodor metal, or a combination of these two materials, and it will be seenthat the device as a Whole is especially adapted for use in connectionwith mines in relieving the latter of water or other matter andconveying it to a distance therefrom. The buckets may be convenientlyused in raising ore or gravel and are especially adapted for employmentin grain elevators. The simplicity of the construction ofthe severalparts make the same easily handled and put up in operative position andthe strength and compactness of the mechanism provide for a durablearrangement..

It is obviously apparent that many minor changes in the construction andarrangement of the several parts might be made and substituted for thoseshown and described without in the least departing from the nature orspirit of the invention.

Having thus described the invention, what is claimed as new is- `In aconveyer of the character set forth, theA combination of Iupper andlower pulleys each of which is supplied with rims which stand beyond theperipheries of the main 35 bodies of the same, and an upper pulleyhaving aseries of dump-troughs which incline toward one 'side and extendthrough one of the rims or heads, a guard strip atone side of eachdump-trough at the top edge thereof, a chute-board adjacentto one sideof the upper pulley and over which the projecting ends of the saiddump-troughs extend, the said chute board being inclined outwardly, areceiving trough under the outer end of the said chuteboard and anendless chain mounted over the pulleys and carrying a series of bucketsformed with upper and lower inwardly sloping ends, and having loopsoreyes on the upper portion of opposite sides thereof, through which areloosely passed link-rods connected at the bottom to a cross-strip and atthe top to a similar cross-strip, substantially as and for the pur-posesspecified.

In testimony whereof yI have signed this 55 specification in thepresence of two subscribing witnesses.
